What is depicted in the signalization plans?

The signalization plans specifically provide details about the electrical wiring of traffic signals. These plans are essential for the correct installation and functioning of traffic signals, including the connections for power supply, ground connections, signal heads, controllers, and other necessary components. Proper understanding of these electrical details ensures that the traffic signal operates safely and effectively, coordinating with the overall traffic control system.

In contrast, the other choices address different aspects of roadway design and construction. Roadway and traffic design standards focus on general design requirements and guidelines but do not delve into the specifics of electrical systems. The quantities of materials required relate to the overall project estimation and billing, while cross-section views of the proposed roadway illustrate the physical dimensions and layout of the road itself, rather than the intricate wiring necessary for traffic signals. Each of these aspects plays a critical role in project planning and execution, but only the electrical wiring focuses on the operational components crucial for traffic signal functionality.
